To elucidate the molecular identity of cardiac pacemaker channels, we screened a human heart cDNA library using a highly conserved neuronal HCN channel segment and identified two cDNAs encoding HCN channels. The hHCN2 cDNA codes for a protein of 889 amino acids. The HCN2 gene is localized on ...

Pacemaker, electronic cardiac-support device that produces rhythmic electrical impulses that take over the regulation of the heartbeat in patients with certain types of heart disease. A healthy human heart contains its own electrical conducting system ca
alsopace-maker, 1884, "one who sets the pace for others," originally a rider or boat that sets the pace for others in training. Meaning "the node of the heart which determines the beat rate" is from 1910; sense of "man-made device for stimulating and regulating heartbeat" (short for...
The cardiac pacemaker is used to maintain an adequate heart rate. The study has also proven the ability of the new pacemaker to correct sinus arrhythmia, an irregularity in the heart rhythm, and prevent deterioration to conditions that may lead to death. ...
Presents a study which evaluated various methods of testing electromagnetic interference due to electric fields on implanted cardiac pacemakers. Use of numerical simulations with millimeter-resolution heterogeneous human body models; Electric properties of cardiac pacemakers; Review of related laboratory studies...

The invention concerns implantable cardiac stimulation devices in general which have at least one stimulation pulse generator (A-STIM; RV-STIM; LV-STIM) to selectively generate a stimulation pulse for delivery to one of at least two different chambers of a heart, said chambers include right and ...
Because pig hearts are anatomically similar to human hearts, this accomplishment shows our device's potential to translate to people. Why it matters Heart disease is the leading cause of death around the world. Annually, over 2 million people undergo open-heart surgery to treat heart problems, ...
Defibrillation and pacing of a human heart from outside the body employs defibrillation circuitry having an electromotive force of less than or equal to approximately 200 volts. Digital circuitry for generating a direct current waveform to the heart is employed....
